The invention discloses a cooling
system for a numerically-controlled
machine tool and relates to the field of numerically-controlled
machine tool equipment. The cooling
system comprises an annular guide rail and a moving mechanism. Multiple temperature sensors are arranged on the lower portion of the annular guide rail. The annular guide rail is internally provided with a cavity. A liquid inlet
pipe is arranged on the annular guide rail, wherein the liquid inlet
pipe communicates with the cavity. The wall of the cavity is provided with a first
solenoid valve. An
infrared sensor is arranged atone side of the first
solenoid valve. A buckling ring is internally provided with an inner cavity. A conveying channel is formed in the buckling ring and a connecting plate. The conveying channel enables a spray head to communicate with the inner cavity. A water pump is arranged at the connection position of the conveying channel and the inner cavity. The inner cavity is internally provided witha
liquid level sensor. The wall of the inner cavity of the buckling ring is provided with a second
solenoid valve. The second solenoid valve can be opposite to the first solenoid valve in position. Bymeans of the cooling
system, the problem that in the workpiece
machining process of a traditional numerically-controlled
machine tool, the spray flow of cooling liquid cannot be adjusted automatically according to the
machining heat quantity is solved; and the cooling system is mainly used for guaranteeing the
cooling effect and workpiece quality.
